Be it known that I, HENRY J ANSSEN, a citizen of the United States, and a resident of \Vyomissing, in the county of Berks, State of Pennsylvania, have invented certain new and useful Improvements in Drive and Stop Mechanism for Braiding-Machines, of which the following isa specification.

My invention relates to an improved driveand-stop mechanism for braiding machines as fully described in connection with the accompanying drawing, the novel features bei ng specificallypointed out in the claims.

Figure 1 is a plan view of abraiding machine having my invention applied thereto. Fig. 2 is an enlarged sectional elevation of the clutch gears andengaging mechanism therefor, showing also the operating connect- .ing rod to the bell-crank and stop mechanism indicated in Fig. 1.

The train of drive gears 2 2 for the bobbin carriers, which are mounted as usual between the top plate 3 and bottom plate 4 of the machine, are driven from a vertical drive shaft 5 at the rear of the machine; said shaft having a fixed gear wheel 6 arranged in mesh with a clutch gealr 7 which is vertically movable into and out of engagement with an intermediate clutch gear 8 arranged in mesh with the train of drive gears 2 Upon the top plate of the machine are mounted a main stop lever 1.0 and a series of supplementary stop levers 11 11, each having an arm 12 fixed, between the plates, to its shaft 13, and a connection 14 from said arm to a common rotary central ring 15 as usual; said stop levers being arranged in the path of the bobbin carriers so as to be swung by any one of the latter when its thread is broken.

Referring to Fig. 2 it will be seen that the intermediate clutch gear 8 is rotatably mounted'upon a bolt 20 extending between the plates 3 and 4; said bolt naving its lower end seated in a step bearing 21 fixed to the bottom plate, while its headed upper end 22 is secured to the top plate by a screw 23 so as to permit of its being readily withdrawn for the purpose of removing or changing the parts mounted upon it. The hub of the intermediate gear 8 referred to extends up ward tothe top plate, and upon this hub is rotatably mounted the clutch gear 7, which is provided with bottom projections 24 the latter is mounted a rotatable cam 27 having upon its upper surface inclined projec- 1 atente'd May 7, 1907. I

adapted to enter corresponding recesses in the gear 8 when said gear 7 is depressed, so as tions 28 which ride upon corresponding bottom projections 29 on a fixed cam ring 30 beneath the top plate 3 of the machine, so that a turning movement of the rotary cam in one direction will serve to positively depress-it, together with the vertically movable gear 8, to engage the latter with the gear 7. The rotary cam 27 providedwith a fixed arm 31 to which is suitably jointed a connecting rod 32 for operating the same.

Referring to Fig. 1 it will be seen that this connecting rod 32 is connected to one arm 35 of a bell-crank which is mounted between the top and bottom plates at the front of the machine and adjacent to the main stop lever 10; and that the other arm 36 of said bellcrank, which is formed with a handle for the operator; is provided with a projecting catch 37 which is adapted to engage a corresponding recess in the extended arm 12 of the main stop lever 10 so as to normally look the bellcrank when it has been moved by the operator so as to engage the two clutch gears as shown in the drawings. The main stop lever 10 also has its extended end 38 so shaped as to serve as a handle fonthe operator.

When the bell-crank 35 36 is free, the clutch gear ,7 is raised out of engagement with the clutch gear 8 by the spring 25, and

is turned idly by the main drive gear 6. To start the machine the operator merely turns the bell-crank arm 36 until it is locked to the main stop-lever arm 12 by the catch 37, the clutch gears being thus forced into engagement by the action of the rotary cam 27. When he wishes to stop the machine he merely pulls upon the end of the main stop lever 10 thereby releasing the catch of the bell-crank and se arating the clutch gears; or in case of brea age of a thread the same releasing effect is produced automatically by the action of the carrier upon one of the series of stop levers. The starting arm 36 of the bell crank projects beyond the plate of the machine so as to be very readily moved laterally by the operator as required and the control of the machine is at all times 'positively and satisfactorily provided for.

What I claim is 1. In a braiding machine a drive and stop mechanism comprising a drive gear, a springreleased clutch gear, a rotary cam mounted upon the gear axis, for engaging said gears, a 10' C utch operating lever connected to said rotary cam, and a stop lever provided with locking means arranged to normally hold said clutch lever in its gear-engaging position, substantiallyas set forth.

2. In abraizling machine a drive and stop mechanism comprising a drive gear, a springreleased clutch gear, a rotary cam for engag- ,ing said gears, a bell crank clutch-operating lever having one arm linked to said rotary cam, and a stop lever having a locking arm engage the other arm of sai bell-crank lever {to hold it in gear-engaging position, substan tially as set forth. I u 3. In a braiding machine the combination with the top and bottom plates and the train .Inovable therevvith and ada ted to normally I of carrier drive gears, of a draw-out boltre-' movably mounted between said plates, an intermediate clutch gear, a spring-released engaging clutch gear and a rotarvcam all mounted upon said bolt, and a ed cam and automatic stop mechanism cooperating v with said rotary cam, substantially as set forth.
